ROERT E. BURKE, OF PHILLIPSBURG, NEV JERSEY.

VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 426,237, dated April 22, 1890.

Application filed December 28, 1889. Serial No. 335,260. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, ROBERT E. BURKE, of Phillipsburg, in the county of Warren and State of New Jersey, have invented a new and useful Improvement in Ventilators, of which the following is a full, clear, and exact description.

My invention. relates to an improvement in ventilators especially adapted for use in connection with railway-cars, and has for its object to provide a means whereby ventilation may be effected at each side Without creating a draft, and whereby the possibilities of dust or cinders entering with the air will be effectually avoided.

A further object ofthe invention is to provide a simple device capable of attachment to a car after the same has been built, and which may be manipulated conveniently by a person within the car without raising the window.

The object of the invention is also to provide a means whereby the position of the device may be changed to suit the direction in which the car may be traveling.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a partial side elevation of a railway-coach, partly in section, illustrating the application of the ventilator. Fig. 2 is a partial inside elevation of one of the windows of a car, illustrating the application of the ventilator to the lower rail of the Windowframe. Fig. 3 is a vertical section taken on line x o: of Fie. 2. Fig. 4.- is a horizontal section on line/gy of Fig. 25 and Fig. 5 is an elevation of yone latch, the cover-plate being removed and the operating-pin in section.

In carrying out the invention the ventilators are preferably located one beneath each window 10 of a car in the bottom rail 11 of the window-frame 12; but, if found desirable, the ventilators may be placed between the ioor and the window, between the windows, or at any other point in the sides of thecar.

If the ventilators are placed in the bottom rail of a win d ow-sash, as illustrated, the outer cesses 13 and 14, separated by a central vertical rib l5, as best shown in Fig. 4, and to the outer end wall of each recess a deilectingshutter is hinged, which shutters are designated in the drawings as 16 and 17. Then the shutters are closed, they completely fill the recesses and contact with the opposite side surfaces of the rib 15, their outer faces being preferably flush with the outer side surface of the window-frame. In each recessed surface of the sash-rail ll a series of apertures or openings 18 are produced, and in the inner face of the sash-rail at or near each end a recess 19 is formed, as best shown in Fig. 5, and each recess 19 is covered by a plate 20, provided, preferably, with a horizontal slot 21 and a vertical slot 22. Through the horizontal slot 21 of each plate a pin or keeper 23 is passed and secured to the de iiecting-shutter near its hinged end. That portion of the recess 19 in which the pin is located extends through the sash-rail, as shown in Fig. 1L. The pin or keeper passes at an inoline into the hinged end of the shutter from the rear, so that the force applied in opening the shutter will be applied inline with its din rection of movement. A person can open the shutter by pushing with much less force than if the pin entered the shutter at right angles, as will be readily appreciated. In each recess 19, between its rear wall and the plate 20, a latch 24- is pivoted at one end. Each of said latches consists, preferably, of a body p0rtion a, capable of vertical movement in the recess, and is provided with a lug a upon the under edge, about midway of the same, which lug, when the latch is carried downward to a locked position, is adapted to pass to one or the other side of the pin 23, as shown in Figs. 3 and 5. The free end of the latch projects outward through the vertical slot 22 in the plate 2O and is provided with ahead a2.

Each shutter is operated in the same manner, namely: To open a shutter for purposes of ventilation, the latch is raised and the pin face of the said rail is provided with two reis carried in the direction of the ven tilatingopenings 18, as shown to the left in Fig. 4,'

and as the latch is then lowered the pin is prevented from moving back by the lug a of the latch contacting with its outer side. The motion of the caris -prevented from releasing the pin from the latchby reason of the lug of the latter Ybeing of sufiicient length to extend some distance below the pin 23. When the pin is carried to the outer end of the slot 21, the shutter is closed, and the lug of the latch retains the shutter in this position by contactin g with the forward side of the pin. One I shutter only is opened when the device is applied to railway-cars, which is the one located at the forward side of the window or nearest the advancing end of the car. Vhen this shutter is opened, it detiects from the openings 18 uncovered thereby any cinders, dust, or Smoke thrown off by the engine, and by reason of the forward movement of the car a suction is created' at the rear of the open shutter, vwhereby pure air is constantly forced through the openings 18 uncovered by the; shutter 'into the car.

I desire it to be distinctly understood that although 'I have described my invention as applied to a railway-car it is capable of ehi-- cient and successful application to a dwelling, for instance, or other fixed structures whereventilation is desired unaccompanied by draft.'

Having thus fully described my invention, I claim as new and desire to secure by Letters; Patent 1. The combination, with the body portion having an .air-inlet, of a deecting-shutter hinged to the outer side of the body to swing over itsY air-inlet, a combined push-pin and keeper extending through an opening in the body from the inside thereof and connected at its outer end with the hinged end of the shutter, and a latch engaging the said pin when in its projected or retracted position to lock the shutter open or closed, substantially as set forth.

2. The combination, with the body having air-inlet openings and a slot 19, andashutter hinged adjacent to said slot 19, of a plate 2O on the inner side of the body over the slot 19 and provided with a longitudinal slot 14, registering therewith, and a vertical slot 22, adjacent to the inner end of the slot 21, a combined keeper and push-pin 23, extending through both of said slots 19 14, connected at its outer end with the hinged end of the shutter and provided at its inner end with a head or stop of greater width than slot 2O to limit its outward movement, a verticallyswinging latch 24: between the plate and body and having a handle projecting through the slot 22, and a lug a to engage the said keeper and push-pin in its projected or retracted positions and lock the shutter open or closed, substantially as set forth.
